In contrast to simple respiratory gating, respiratory compensation techniques acquire data continuously throughout the respiratory cycle. The low-amplitude phase-encode steps (very sensitive to motion) are acquired during expiration while the high-amplitude phase-encode steps (less sensitive to motion) ...
The Society of Skeletal Radiology (SSR) Practice Guidelines and Technical Standards Committee identified musculoskeletal infection as a White Paper topic, and selected a Committee, tasked with developing a consensus on nomenclature for MRI of musculoskeletal infection outside the spine. The objective of ...

despite the magnetic ordering, then it is an antiferromagnet. All of thesealignmenteffects only occur at temperatures below a certain critical temperature, called the Curie temperature (for ferromagnets and ferrimagnets) or the Néel temperature (for antiferromagnets). Typicalferromagneticmaterials are iro...
Each matrix entry represents the upregulated (bottom left) and downregulated (top right) number of DEGs with a fold change ≥ 2 in expression level. Subcortical and occipital regions exhibit marked heterogeneous patterns (red) in contrast to the rest cortical regions (blue). DEGs, differentially ...
nausea, dizziness, or allergic reactions. They can also be expensive, and the confined space of the MRI machine can be unsettling. In contrast, ultrasounds are less expensive, typically costing a few hundred dollars, and offer a more comfortable experience without the need for contrast,” she ...
whole-liver imaging and combines 3D SPGR and ASSET (up to 3X) to deliver reduced scan time and extended coverage without compromising in-plane resolution. LAVA also uses an optimized inversion pulse and a view ordering technique that yields enhanced image contrast and robust, uniform fat ...
